研究了d=3,±J分布,无规键Ising模型中自旋玻璃-铁磁-顺磁多临界点的临界性.利用T-34阶的高温展开,我们估计多临界点N位于Nishimori线上,Tc/J=1.690±0.016。沿着这条线,临界指数γ=1.80±0.15,v=0-85±0.08。后者显然与严格的指数不等式v≥2/d是一致的
We study the criticality at the spin-glass-ferromagnetic-paramagnetic multicritical point in the d=3, ±J distribution, random-bond Ising model. Using high-temperature expansions to order T -34 , we estimate that the multicritical point N lies on the Nishimori line at T c /J=1.690±0.016. Along this line the critical exponents are found to be γ=1.80±0.15 and v=0-85±0.08. The latter is clearly consistent with the rigorous exponent inequality v≥2/d
