T. Nakata et al., INTERCOMPARISON OF A SINGLE SHEET TESTER FOR AMORPHOUS-ALLOYS BY ROUND-ROBIN MEASUREMENTS IN JAPAN, Journal of magnetism and magnetic materials, 160, 1996, pp. 119-122
A Japanese intercomparison of measurements of the magnetic properties
of amorphous ribbons was carried out, Although the results for power l
oss are in fairly good agreement, the results for peak magnetic field
strength and apparent power differ considerably.
