Physical properties of R$_2$Co$_6$Al$_{20-\delta}$ (R = Gd-Tm, Y) single crystals
Heavy rare-earth R2Co6Al20-δ single crystals adopt orthorhombic Imma structure with Al deficiency δ ~0.7-0.9 and exhibit AFM ordering (TN 1.8-11.8 K) with two transitions in Gd/Tb and clear deviation from de Gennes scaling.
