1. Available appointment time: User can reserve time for every Monday to Friday 09:00am to 13:00pm (1 period= 4 hours)
2. Users can at most reserve one period (4 hours) at one time. Users can reserve next available period only after experiment is finished.
3. Users should give the sample and preferred experimental conditions to the instrument manager at least one to two days before the reserved time slot.

Assisted User measurements:

1. Users should pass the certification of the training course for “Superconducting Quantum Interference Device” class and licensed specifically for the SQUID-VSM, in order to reserve the operation time.
2. Available appointment time: User can reserve time for every Monday to Friday 09:00am to 13:00pm (1 period= 4 hours)
3. Users can at most reserve one period (4 hours) at one time. Users can reserve next available period only after experiment is finished.

Miscellaneous rules

For the benefit of fair access of all users intending to access this delicate SQUID-VSM, users shall abide by the following tules:

1. Users from the same research group should not reserve more than 5 periods (1 periods=4 hours) in a month (including both the entrusted and assisted operation time slots)
2. If a user misses his or her appointment, the following reservation will be banned for two weeks. Every appointment absence laps will result in two weeks of suspension of right to time slot reservation.
3. Users must sign a legal binding agreement if that the instrument or its peripheral attachment is damaged due to the users’ misoperation, the incurred repair cost shall be covered by the user and users’ group.

Additional technical note:

The measurement time between SQUID-VSM and MPMS:

• For M-T measurement time (Zero Field Cooling 2 K ~ 300 K):

VSM takes approximately 2 hours

MPMS takes approximately 3 and half hours

• For M-H measurement time (1 Tesla ~ -1 Tesla): assuming the measurement resolution is 500 Oe.

VSM needs about 5~10 seconds to stabilize at a specified magnetic field strength. The estimated measurement time is approximately 2 hours.

MPMS needs about 30~60 second to stabilize at a specified magnetic field strength. The estimated measurement time is approximately 4 hours.

Measurement tips for SQUID-VSM:

•         If the magnetic properties of your sample is unknown, an initial survey scan with a wide range -5T to 5T measurement span and a coarse 5000 Oe step is advised. If your sample is ferromagnetic, we advise an initial survey scan from -1T to 1T and a 1000 Oe step. Further optimization can be made afterward based on the obtained signal from the initial survey scans.•         For the M-T measurements, we advise using test sequence for the initial survey scan with a temperature range from 5~300 K. This will take approximately 2 hours. When you know your sample property better, the measurement procedure and parameters can be further optimized.

Suggestions on sample preparation:

• Please be present in the SQUID-VSM laboratory one to two days in advance to prepare your measurement samples.
• If your samples are in powder or crystal form, you can use plastic capsule or food wrap to encapsulate the samples.
• If your samples are flakes or coated on substrates, you can attach your samples to a straw for experiment.
• If you have special request for your experiment, either in measurement or sample preparation, please discuss with the SQUID-VSM instrument manager.

Important note on liquid helium:

• If the liquid helium reserve is lower than 3 liters, or there is any error or anomalous behaviors with the SQUID-VSM instrument, please contact the instrument manager.

Application procedure：To apply for instrumentation access, the user should first fill out an application form by contacting the facility secretarial assistant and ask his or her supervisor to sign the form. After filing the application, the user can make an appointment with the instrument manger to arrange the access time slot. The user, if already licensed, can directly use the instrument after the machine time is allocated. The user, if not yet licensed, must either (a) obtain an operation license from the instrument manager, or (b) entrust the instrument manager for measurements. If the user wishes to obtain operation license, he or she must first practice the needed full measurement procedure along with a licensed user or the instrument manager at least twice before a license granting request can be arranged.

Users must sign a legally binding agreement stating

1. Access card must not be used by others except the one for which the card is intended. Any violation will lead to indefinite suspension of user access right.
2. Any working area used for the experiments must be thoroughly cleaned and organized after the measurements. The instrument might be kept at the proper state ready for the next user. Violator will be warned and repeated offenders will be indefinitely suspended for instrument access.
3. All used tools should be returned and not misplaced. Any material used should be properly kept or disposed following all needed safety regulations. Violator will be warned and repeated offenders will be indefinitely suspended for instrument access.
4. Users shall not change the instrument’s settings without prior authorization from the instrument manager. Any single offense will lead to indefinite suspension of instrument user access right.
5. Users are requested to fill out the instrument experiment log book clearly, and report any instrument anomaly.
6. In case of instrument damage, the user and his or her supervisor should discuss with the facility core members. If the instrument is seriously misoperated, the user access will be terminated unless a shared repair cost is arranged and agreed by the both sides.

Above instrument regulations will be yearly re-examined and revised by the facility executive board.
