  • We Show How A Quantity Calculated From Isothermal Magnetization Curves
  • The Magnetic Entropy Change
  • ΔSm
  • Is Affected By The Erroneous Data
  • As ΔSm Is A Measure Of The Magnetocaloric Effect
  • The Discrepancies Demonstrated Here Are More Severe Close To A Peak In ΔSm
  • Which Is Precisely The Quantity That Is Of Interest And Reported On In The Literature From Possibly
  • We Also Demonstrate How
  • Through Simple Measurements And Without A Direct Measurement Of The Sample Temperature
  • One Can Determine An Appropriate Sweep-Rate Of The Magnetic Field
