Density of states of Y2Co,4B and also the local density of states of Y and Co atoms are calculated by making use of the tight-binding d-band model and by recursion method. Local magnetic moments on Co atoms are calculated from the computed local density of states (Inoue and Shimizu 1986b). 

Shimizu (1977, 1978, 1980, 1981) regarded the magnetovolume effects in the framework of a thermodynamic approach with the help of mean field and band models. He expanded the free energy in a power series of magnetization and relative volume change AV/F. The Curie temperature shift under compression was determined from the position of the spin susceptibility pole x T,P) = 0. From this condition the formula for calculating dJc/dP was derived (Inoue and Shimizu 1985) ... 

Using eqs. (37) and (38) and the models proposed by Lang and Ehrenreich (1968), Kanamori (1963), Heine (1967), the equation for the pressure derivative of the Curie temperature in the s-d model was derived (Inoue and Shimizu 1980)... 

Originally, Inoue and Shimizu (1980) regarded the alloys with paramagnetic collective d-electrons over the whole temperature range. Subsequently this model was used also for lanthanide-3 dTM alloys with ferromagnetic order in the collective electron system (Inoue and Shimizu 1984, 1986). The following two types of d-electron susceptibility temperature dependences were used ... 

Inoue and Shimizu (1988), in the framework of the model described above, calculated the volume dependence of the transition temperature to the magnetically ordered state at the boundary between the first- and second-order transition, see fig. 7. Thus, pressiure can alter the order of the magnetic phase transition. Such a behavior can be explained by the decrease of the molecular field acting on the 3d-electron subsystem which causes the reduction of the Co moment (Inoue and Shimizu 1988).
