The main field of research

  • Field dependences and temperature dependences of magnetization and magnetic susceptibility of samples with small value of magnetic moment ;
  • Spontaneous and field induced phase transitions;
  • Relaxation processes of magnetization;
  • Reversal processes in magnetic materials.

Equipment
 

1. SQUID-magnetometer MPMS-XL5


    SQUID-magnetometer ("Quantum Design", ) is intended for magnetic properties investigation (magnetization and magnetic susceptibility) of samples with small value of magnetic moment.

   Measurements can be provided with different materials: single crystals, polycrystalline samples, thin films, powders et al.

 


 


Basic technical characteristics:

 

  • range of measurement of the magnetic moment 5 EMU;
  • differential sensitivity ≤10-8 EMU at the measurement of magnetic moment of sample in a field up to 0,25 esla and ≤210-7 EMU in a field up to 5 sl;
  • magnetic field range 5 sl;
  • temperature range from 1,9 to 400 ;
  • temperature stability for sample space 0,5%.

The equipment has a few additional options:

 

) for magnetic anisotropy studies - automatic device for horizontal (from 0 to 360, increment = 0,1) or vertical (360, increment = 0,1)  sample rotation

 

 

) Fiber Optic Sample Holder (FOSH) for magnetooptical investigation

 

 

 

2. Laboratory electronic scales XA 60, "RAGWAG" Poland

 

  • weighing range - from 0,001 to 60 g;
  • resolution - 0,01 mg;
