The magnetic pressure phase diagram of CeRu2(Ge,Si)2 studied by neutron diffraction

Previously, an analogy has been observed between the application of hydrostatic and chemical pressure on the properties of CeRu2(Ge,Si)2 alloys. In order to test this analogy on a microscopic scale we examined the magnetic pressure phase diagram of single–crystalline CeRu2Ge2 and CeRu2(Ge0.7Si0.3)2 by means of elastic neutron scattering. The results from our microscopic study of the p – x – T phase diagram of CeRu2(Ge,Si)2 are in full agreement with those previously determined by means of bulk experiments.
