- •
Direct MCE measurements in AC magnetic fields up to 22 Hz were carried out.
- •
AC magnetic field source with ΔH = 0.62 T and frequencies up to 50 Hz was created.
- •
The MCE in Gd shows inconsiderable changes with field frequency.
- •
In Ni2.07Co0.09Mn0.84Ga Heusler alloy the MCE vanishes at frequencies about 20 Hz.
- •
In Fe48Rh52 in weak AC field an irreversibility of the AFM-FM transition is observed.
