As a part of an extensive study on the new geometric frustration series M2(OH)3X on deformed pyrochlore lattice, we have found an exotic antiferromagnetic order in atacamite-structure Ni2(OH)3Cl. Strong frustration exists in Ni2(OH)3Cl with antiferromagnetic transition below TN=4 K. While neutron diffraction witnessed unambiguously a long-range order, there is no signature of an order as detected by μSR. Instead, the detected local field is dynamically fluctuating at zero field. The present material may exemplify a novel type of antiferromagnetic order recently predicted for Heisenberg spins on pyrochlore lattice, wherein the squared Fourier amplitude orders but the amplitude itself fluctuates rapidly.
