The magnetic moments of Tb, Dy, or Er ions in dilute Sc single-crystal alloys have been measured in fields up to 280 × 105 A/m (350 kOe). The Zeeman energies in this high field are comparable to the total crystal-field splittings. This gives rise to

The magnetization of Tb single crystals was measured in magnetic fields to 34T along the hard direction at temperature of 1.8, 4.2, 65.5 and 77K, and along with easy direction at 4.2 and 77K. The data are compared with the results of a self-consisten

DC magnetization measurements at 4.2 K in applied fields up to 340 kG are re- ported. The smooth behaviour of the magnetization curves confirms that the anisotropy may be attributed to the octahedral site Mn ions.

In this paper the conditions for a fast feedback of an ignition-controlled current regulator with predominantly inductive load are examined. The average current can be made independent of the load both when a low impedance load with external coil is

Spin‐lattice relaxation in a paramagnetic salt at liquid‐helium temperatures has been studied by observing the time dependence of the magnetization in a pulsed magnetic field. The nearly trapezoidal field pulse can be kept constant during 0.3 sec
