Even if Weyl semimetals are characterized by quasiparticles with well-defined
chirality, exploiting this experimentally is severely hampered by Weyl
lattice-fermions coming in pairs with opposite chirality, typically causing the
net chirality picked up by experimental probes to vanish. Here we show this
issue can be circumvented in a controlled manner when both time-reversal- and
inversion- symmetry are broken. To this end, we investigate
chirality-disbalance in the carbide family RMC2​ (R a rare-earth and M a
transition metal), showing several members to be Weyl semimetals. Using the
noncentrosymmetric ferromagnet NdRhC2​ as an illustrating example, we show
that an odd number of Weyl nodes can be stabilized at its Fermi surface by
properly tilting its magnetization. The tilt direction determines the sign of
the resulting net chirality, opening up a simple route to control it.Comment: 7 pages, 3 figures, 1 table, and Supplemental Informatio
