Title: Magnetic-field effects on the fragile antiferromagnetism in YbBiPt

Abstract

We introduce neutron-diffraction data for the cubic-heavy-fermion YbBiPt that show broad magnetic diffraction peaks due to the fragile short-range antiferromagnetic (AFM) order persist under an applied magnetic-field H. Our results for H⊥ [$$\overline{1}10$$] and a temperature of T = 0.14 (1) K reflect that the ($$\frac{1}{2}$$, $$\frac{1}{2}$$, $$\frac{3}{2}$$) magnetic diffraction peak can be described by the same two-peak line shape found for μ 0 H = 0 T below the Néel temperature of T N = 0.4 K . Both components of the peak exist for μ 0 H ≲ 1.4 T , which is well past the AFM phase boundary determined from our new resistivity data. Using neutron-diffraction data taken at T = 0.13(2) K for H ∥ [001] or [110] , we show that domains of short-range AFM order change size throughout the previously determined AFM and non-Fermi liquid regions of the phase diagram, and that the appearance of a magnetic diffraction peak at ($$\frac{1}{2}$$, $$\frac{1}{2}$$, $$\frac{1}{2}$$) at μ 0 H ≈ 0.4 T signals canting of the ordered magnetic moment away from [111] . The continued broadness of the magnetic diffraction peaks under a magnetic field and their persistence across the AFM phase boundary established by detailed transport and thermodynamic experiments present an interesting quandary concerning the nature of YbBiPt's electronic ground state.
