  At low temperature the holes doped into the NiO(2) planes of La(2)NiO(4.133)
by the excess oxygen collect in diagonal stripes that separate narrow
antiferromagnetic domains. The magnetic order drops abruptly to zero at T_m =
110.5 K, but charge order remains with a period of 3a/2. We show that
application of a magnetic field in the regime T > T_m induces staggered
magnetic order of period 3a due to the net magnetic moment of the
high-temperature bond-centered stripes, together with the odd number of Ni
spins across an antiferromagnetic domain.
