Grinding Mechanical working Comarp - Milanese consortium

Mechanical grinding Co.m.ar.p carries out the grinding operations, i.e. the processes obtained by abrasion exerted by a grinding wheel. The speed of rotation of the grinding wheel, made up of abrasive material, allows it to remove a moderate quantity of material from the surface of the part to be worked with considerable precision.

Spin-glass behaviour in GdMnAl obtained by mechanical grinding

Jun 13, 2002  1.. IntroductionRecently, we have shown that the mechanical grinding applied to the intermetallic GdMn 2 induces a magnetic transition from antiferromagnetism (initial sample) to ferromagnetism (sample milled at high speed) below T C =105(5) K .A similar result was obtained by application of hydrostatic pressure on GdMn 2.This magnetic transition can be explained considering
