The phase diagram of the title system is remarkably rich, exhibiting regions of long-range antiferromagnetic order, short-range (spin-glass-like) order, high temperature superconductivity, or none of these. Here, the phase diagram is reviewed, with a

The 11B NMR spectra of xRb2S+(1−x)B2S3 glasses in the range 0⩽x⩽0.75 and of xCs2S+(1−x)B2S3 glasses in the range 0⩽x⩽0.60 are reported. The addition of Rb2S to B2S3 creates on average approximately two and one-half tetrahedral borons for

The nuclear magnetic resonance of the metal nucleus 45Sc shows anomalous spin–lattice relaxation at high temperatures (T≥800 K) in scandium dihydride and dideuteride. The anomalous rate R1A is represented by R1A=Aexp(−U/kBT), with an effective
