μ′ represents the energy stored, while μ″ is the energy loss dissipated within the ferrite. The ratio of μ″ over μ′ is defined as magnetic loss tangent (tan δμ = μ″/μ′), which describes the power lost versus power stored in a ferrite. The magnetic loss tangent consists ...
Magnetic measurements were performed with a Quantum Design MPMS SQUID magnetometer, equipped with a superconducting magnet (a solenoid of superconducting wire), which produces magnetic fields in the range from −7 T to +7 T. The samples in the form of powders were immobilized in an epoxy resin...
A solenoid made of copper wire winded in a tight helical shape was used as a device to generate a homogeneous magnetic field (field strength invariant in space and time). As shown in Figure 1A, the field B generated was uniformly directed parallel to the solenoid axis via passing an electri...
