Fractalisation drives crystalline states in the frustrated spin system SrCu$_2$(BO$_3$)$_2$

ORAL

Abstract

Geometrical frustration in the spin dimer material SrCu$_{2}$(BO$_{3})_{2}$ leads to a singlet Shastry-Sutherland groundstate at low magnetic fields, but complex spin superstructures at higher fields. Our magnetisation measurements reveal a fine substructure of quantum Hall-like plateaux at all $1/q$ ratios $2
