The crystallographic paramerers of compounds MnAs. ,P, (Ofi,vfi0.275)are determined as a function of temperature between about 100 and 600 K. It isfound that these crystals except for MnAs take a MnP type structure in lowtemperature side and transform to a Nips type at critical temperatures. Thesestructural transitions are of second kind and accompanied with very large dilation( - 10 '%) of crystal volume. In order to see the relationship between the structuraland magnetic properties, the temperature variation of magnetic susceptibilitiesof the compounds is also measured. Simple analysis of the experimental results,based on the Curie-Weiss law, reveals the way in which the spin value of Mn atomsand the exchange interaction between them depend on the crystal voluem (orlattice parameter).
