As a native English speaker, I would suggest something along these lines:
I really enjoyed your paper from 1980 on the mating habits of lemmings.
I really enjoyed your paper titled: "Lemmings--The Randy Devils," that you published in 1980.
You mentioned 'love' in your original question, so there is no need to hold back on using 'really enjoyed' instead of just 'enjoyed.'
Using the word 'year' with a year is not typically done by native speakers unless the year itself is very important to the thought: "…your book about the year 1984", or "I'm a time traveler from the year 2151."
The idea of using 'interesting' can suggest a somewhat tepid response. See this article from ELL.
I hope this helps.
