  A binary intermetallic compound Er5Pd2 has been investigated using dc and ac
magnetic susceptibilities, magnetic memory effect, isothermal magnetization,
non-linear dc susceptibility, heat capacity and magnetocaloric effect studies.
Interestingly, even though the compound does not show geometrical frustration
it undergoes glassy magnetic phase transition below 17.2 K. Investigation of dc
magnetisation and heat capacity data divulged absence of long-ranged magnetic
ordering. Through magnetic memory effect, time dependent magnetization and ac
susceptibility studies it was revealed that the compound undergoes glass-like
freezing below 17.2 K. Analysis of frequency dependence of this transition
temperature through scaling and Arrhenius law; along with Mydosh parameter
indicate, that the dynamics in Er5Pd2 is due to the presence of strongly
interacting superspins rather than individual spins. This phase transition was
further investigated by non-linear dc susceptibility and was characterized by
static critical exponents {\gamma} and {\delta}. Our results indicate that this
compound show signature of superspin glass at low temperature. Additionally,
both conventional and inverse magnetocaloric effect was observed with large
value of magnetic entropy change and relative cooling power. Our results
suggest that Er5Pd2 can be classified as a superspin glass system with large
magnetocaloric effect.
