New superconducting modifications of yttrium
Brandt N.B., Berman I.V., Kurkin Yu.P.
The resistivity of Y was investigated in the range of pressures Ρ up to 160 kbar and at temperatures 0.1-4.2 °K. At Ρ up to 110 kbar, Y is not superconducting down to 0.1 °K. It appears that three different crystalline modifications of Y are stable in the pressure range 110-160 kbar.
