Abstract

We study the influence of hydrostatic pressure on a transition from antiferromagnetic (afm.) to ferromagnetic (fm.) order that occurs in the intermetallic series Tb_1-xNiAl and TbNi_1-xCu_xA. between x = 0 and x = 0.1. This is a remarkable transition, because (1) magnetic domains of both types coexist in parallel, (2) in the ordered phase the balance between both depends on temperature. The ordering temperature (T_C = 47 K) and the spin direction in the unit cell remain unchanged. First results are presented which show that in fm. compounds under pressure afm. ordering is re-established. In Tb_0.95Y_0.05NiAl at T = 2 K and p = 7 kbar, we find a domain ratio of afm:fm = 75:25 compared to afm:fm = 4:96 at ambient pressure.
