The Nd3+ doped LaAlO3 crystal is a good candidate of a polarized 139La target for the search of the P-odd and T-odd interaction in the low-energy neutron absorption of 139La. As the first step for realizing the polarized 139La target, we grow the undoped LaAlO3 crystal and the La1−xNdxAlO3 (x = 5 ×104) crystal by floating-zone method with four halogen lamps. The ESR measurements of Nd3+ in the latter crystal indicated that the linewidth was about 6 gauss, whose value is the same as the crystal in which 50 % 139La polarization was achieved in the previous DNP experiment. As the result, the crystals grown by this method can be applicable to the target study for the T-violation search.
