The temperature dependence of the magnetic penetration depth of {ZrNi$_2$Ga} is consistent with a single isotropic gap s-wave BCS superconductor. The gap energy is \\Delta(0)=0.44(1) meV and the magnetic penetration depth, \\lambda(0), is 310(5) nm. Furthermore, we show evidence of a possible cross-over from an square flux line lattice to a hexagonal lattice at low temperatures. No evidence of time reversal symmetry breaking has been observed as mi","authors_text":"A.D. Hillier, D. McK Paul, N.
