At low temperature the holes doped into the NiO{sub 2} planes of La{sub 2}NiO{sub 4.133} by the excess oxygen collect in diagonal stripes that separate narrow antiferromagnetic domains. The magnetic order drops abruptly to zero at T{sub m}=110.5 K, but charge order remains with a period of (3)/(2)a. We show that application of a magnetic field in the regime T{gt}T{sub 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. {copyright} {ital 1997} {ital The American Physical Society}
