• We present a comparative study of bosonic languages to describe one-dimensional Heisenberg ferrimagnets.The ferrimagnetic Schwinger-boson mean-field theory demonstrated by Wu et al., the antiferromagnetic modifiedspin-wave theory designed by Takahashi, and its ferrimagnetic variant proposed by Yamamoto et al. areemployed to calculate the energy structure and the thermodynamics of various ferrimagnets. A modifiedspin-wave scheme, which introduces a Lagrange multiplier keeping the native energy structure free fromtemperature and thus differs from the original Takahashi scheme, is particularly stressed as a useful tool toinvestigate one-dimensional quantum ferrimagnetism. The antiferromagnetic limit of these descriptions is alsoconsidered.
