The interplay between magnetism and superconductivity in Ho(Ni1xCox)2B2C (x=0, 0.2, .., 1): probing the evolution of magnetic modes
Recently we observed a cascade of magnetic modes in Tb(CoxNi1-x)2B2C: from a LSDW k = (0.55,0,0) state at x = 0, to a collinear k = ( 0.5,0,0.5) AFM state at x = 0.2, 0.4; then a transverse c axis modulated k = (0,0,1/3)mode at x = 0.6, and finally a simple FM mode at x = 0.8, 1. The observation of the k = (0,0,1/3) mode, which has not been observed before in borocarbides, confirms the prediction by Rhee et al. [PRB51,15585(1995)] of a peak in the generalized susceptibility. Although this model explains the surge of this mode, however it fails to explain the surge of the other modes: this is most probably due to dis-consideration of the interplay between superconductivity (SUP) and magnetism (MAG). Such an approach was undertaken by Bertussi et al [PRB79,220513(2009}] who did predict a co-existance of SUP and MAG and also the surge of a cascade of magnetic modes if MAG and SUP couplings are properly tuned. In fact TB(CoNi)2B2C can be considered as non-SUP limit of their phase diagram. To explore fully this model we proposed to investigate this interplay in Ho(CoxNi1-x)2B2C wherein x=0 (x=1) is a AFM SUP (normal FM). Does the modes of this series verify the predicted phase diagram?
