Evidence of pressure-induced antiferromagnetism in ferromagneticHo0.4Gd0.6

Physical Review B (Condensed Matter)
Preserved Fulltext
The rare earth alloy Ho 0.4 Gd 0.6 was examined under uniaxial pressure applied along the c axis by means of magnetic susceptibility vs temperature. At ambient pressure the compound happened to be ferromagnetic at all temperatures where magnetic ordering occurs. Nevertheless, at pressures larger than p*ϭ700 bars there is clear evidence of an antiferromagnetic phase ͑likely to be helical one͒ that occurs just below the magnetic ordering temperature. This result is consistent with the hypothesis
