Neutron powder diffraction study on the magnetic structure of NdPd$$_5$$Al$$_2$$

Magnetic structure of NdPd$$_5$$Al$$_2$$ has been studied by means of neutron powder diffraction. We observed remarkable magnetic reflections with the modulation vector $$q$$= (1/2 0 0) below the ordering temperature $$T_{rm N}$$ = 1.2 K. We found a collinear magnetic structure of Nd moment of 2.9(1) $${mu}_{rm B}$$ at 0.3 K parallel to the $$c$$-axis, where the ferromagnetically ordered $$a$$ planes stack with four Nd layer period of ++-- sequence along the $$a$$ direction with the distance between adjuscent Nd layers to be $$a/2$$. This is very similar to CePd$$_5$$Al$$_2$$ with $$q$$ = (0.23 0.23 0) and the Ce moment parallel to the $$c$$-axis. These structures with in-plane modulation $$q_{|}$$ is a consequence of the two dimensional nature of fermi surface topology in this family, coming from unique crystal structure with very long tetragonal unit cell and large distance $$>$$ 7${AA}$ between the rare earth layers separated by Al and two Pd layers.

We observed remarkable magnetic reflections with the modulation vector $$q$$ = (1/2 0 0) below the ordering temperature $$T_{rm N}$$ = 1.2 K. We found a collinear magnetic structure of Nd moment of 2.9(1) $${mu}_{rm B}$$ at 0.3 K parallel to the $$c$$-axis, where the ferromagnetically ordered $$a$$ planes stack with four Nd layer period of ++ ${rm - -}$ sequence along the $$a$$ direction with the distance between adjacent Nd layers to be $$a/2$$. This is very similar to CePd$$_5$$Al$$_2$$ with $$q$$ = (0.23 0.23 0) and the Ce moment parallel to the $$c$$-axis. These structures with in-plane modulation $$q_{|}$$ is a consequence of the two dimensional nature of fermi surface topology in this family, coming from unique crystal structure with very long tetragonal unit cell and large distance $$>$$ 7${AA}$ between the rare earth layers separated by Al and two Pd layers.
